So, I've been looking through all the forum threads I can find about resetting maps, and aside from the way used in SkyWars (creating a zip backup), I've found another way that uses setAutoSave(false);, and then you need to just unload and reload the level, and it goes back to how it was. Is this still a working method? Or has it been changed since around a year ago? Couldn't find any post newer than mid 2018, so just checking here before I go ahead and use the method. (Also getting confused on using a repeating task to schedule the map reset, but that's probably for another thread.)
